a)0,5⁵= _____________
b)1,5³=_____________
$c) \sqrt{1.96 = }$
$d) \sqrt{0.64 = }$



​

Answer 1

Resposta:

Explicação passo a passo:

a) 0,5²

$(\frac{5}{10} )^{5} = (\frac{1}{2} )^{5} =\frac{1^{5} }{2^{5} } =\frac{1}{32}$

b) 1,5³

$(\frac{15}{10} )^{3} = (\frac{3}{5} )^{3} =\frac{3^{3} }{5^{3} } =\frac{27}{125}$

c) √1,96

$\sqrt{\frac{196}{100} } = \frac{\sqrt{196} }{\sqrt{100} } =\frac{14}{10} =\frac{7}{5}$

d) √0,64

$\sqrt{\frac{64}{100} } = \frac{\sqrt{64} }{\sqrt{100} } =\frac{8}{10} =\frac{4}{5}$

Answer 2

Explicação passo-a-passo:

$a)0.5 {}^{5} = 0.5 \times 0.5 \times 0.5 \times 0.5 \times 0.5 = 0.03125$

$b)(1.5) {}^{3} = 1.5 \times 1.5 \times 1.5 = 3.375$

$c) \sqrt{1.96} = \sqrt{ \frac{196}{100} } = \frac{ \sqrt{196} }{ \sqrt{100} } = \frac{14}{10} = \frac{7}{5}$

$d) \sqrt{0.64} = \sqrt{ \frac{64}{100} } = \frac{ \sqrt{64} }{ \sqrt{100} } = \frac{8}{10} = \frac{4}{5}$
